Kyle Singler and Chauncey Billups hit consecutive 3s as the Pistons (2-4) took the lead for good. Washington's Glen Rice missed a 3-point heave as the buzzer sounded.

Bradley Beal had 17 points and Seraphin added 14 points and 10 rebounds for the Wizards (1-5), who lost their third straight preseason game.
